WHIFFLETREE-HOOK.

SPECIFICATION forming part of Letters Patent No. 467,566, dated January 26, 1892.

Application filed May 1% 1891. Serial No. 892,461. (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM F. WHITE, of the city of Troy, county of Etensselaer, and State of New York, have invented a new and useful Improvement in \Vhiftletree-Snaps, of which the following is a specification.

My invention relates to an improvement in spring-snaps to adapt them for use upon whiftletrees for trace connection.

Accompanying this specification to form a part of it there is a sheet of drawings containing two figures illustrating my invention,with the same designation of parts by letter reference used inboth of them.

In the illustrations, Figure 1 shows in perspective my improved socket-snap as applied to each end of a 'whiffletree. Fig. 2 is a section taken through a part of the whifiletree and also through the center of the snap-sockct, snap-hook, snap-bolt spring, and fingerpiece, with the parts shown on a larger size than in Fig. 1.

Theseveral parts of the apparatus thus illustrated are designated by letter reference, and the function of the parts is described as follows:

The letter WV designates the whifiletree and with the snap shown as attached at each end thereof at Fig. 1.

The letters T designate the thills and crosshead, and T parts of the thills.

The snap S is made with a socket d for receiving the end 6 of the whiflietree, and the letter H designates the snap-hook, the shank h of which projects from the front side of the socket at about right angles to the socketcenter, and this hook end 7L2 curves inwardly toward the outer end of the socket.

The letter C designates a cylinder or tubeform inclosure which is cast integrally with the socket at right angles to its longitudinal center. The rear end of this cylinder or tube is made with a vent-hole O for the exit-passage of dust or water.

The letter D designates a spring arranged within the cylinder 0, and B a snap-bolt arranged within said cylinder, with the rear end of the bolt bearing upon the spring, and isby the latter forced to project through the front end of the cylinder or tube to engage with the end of the hook at h.

The letter J designates a slot made in the side of the cylinder or tube 0, and F a fingerpiece projected through said slot, by which the snap-bolt B is drawn back against the force of the spring for connectinga trace with the hook H.

The hook, its socket, and the tube-form cylinder part of the snap are all cast in one piece, and the socket is secured onto the ends of the whiffletree by means of a bolt or pin shown at p in Fig. 1. As thus made and arrange d,the snap-hook is by its peculiar form and means of connection well adapted to connect with the whiffietree, and it furnishes a convenient means for attaching the traces that is perfectly secure and from which the traces may be easily disconnected when unharnessing.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

A snap-hook for Whiffletrees, made with a socket for attachment to the ends of the latter, said socket having a hook projected from the front side of the socket with the hookshank at right angles thereto and having a slotted tube-form bolt-chamber at the socket end at right angles to the latter, abolt within said chamber operated by means of a spring to engage at its outer end With the inturned end of said hook, and a finger-piece on the bolt projecting through the slot in the boltchamber, substantially as and for the purposes set forth.

Signed at Troy, New York, this 11th day of March, 1891, and in the presence of the two witnesses whose names are hereto written.

- WILLIAM F. WHITE.
